Scientists have created a crystal structure that boosts the interaction between tiny bursts of light and individual electrons, an advance that could be a significant step toward establishing quantum networks in the future.

An international team of researchers from the National Physical Laboratory (NPL), IBM, the University of Edinburgh and Auburn University have shown that a new device concept - a 'squishy' transistor - can overcome the predicted ...

(Phys.org)—Information can never be stored perfectly. Whether on a CD, a hard disk drive, or a piece of papyrus, technological imperfections create noise that limits the preservation of information over time. But even if ...

From their origins in the 1940s as sequestered, room-sized machines designed for military and scientific use, computers have made a rapid march into the mainstream, radically transforming industry, commerce, entertainment ...

(Phys.org) —With the goal of understanding the relation between thermodynamics and quantum mechanics, physicists have recently been investigating the fundamental limits of the smallest possible quantum refrigerator. As ...

(Phys.org) —Researchers are developing a new type of semiconductor technology for future computers and electronics based on "two-dimensional nanocrystals" layered in sheets less than a nanometer thick that could replace ...

(Phys.org) —Remember when each new crop of computers was ever so much faster than the previous models? Well, those good-old days ended about five years ago when the accelerating rate of computing speeds crashed into the ...

A decade ago, a British philosopher put forth the notion that the universe we live in might in fact be a computer simulation run by our descendants. While that seems far-fetched, perhaps even incomprehensible, a team of physicists ...

Even empty gaps have a colour. Now scientists have shown that quantum jumps of electrons can change the colour of gaps between nano-sized balls of gold. The new results, published today in the journal Nature, set a fundamental ...
